Study on temperature effects based on measuring power distribution system of PUF

Hardware for security mechanisms such as authentication, cryptographic protocols, digital rights management and hardware metering depend heavily on the security of embedded secret keys. In the Power Distribution System (PDS) of an IC and describe how these measurements can be applied to a Physical Unclonable Function (PDF). We introduce active temperature control to the PDF analysis. Adding temperature control has two benefits. First, it helps us to improve the stability of the chip temperature. Second, temperature control allows us to subject our PDF to different temperature points between 0 °c and 75°c and characterize the effects on performance.
